    • Transparent Incremental Updates for Genomics Data Analysis Pipelines 

      Pedersen, Edvard; Willassen, Nils Peder; Bongo, Lars Ailo (Chapter; Bokkapittel, 2014)
      A large up-to-date compendium of integrated genomic data is often required for biological data analysis. The compendium can be tens of terabytes in size, and must often be frequently updated with new experimental or meta-data. Manual compendium update is cumbersome, requires a lot of unnecessary computation, and it may result in errors or inconsistencies in the compendium. We propose a transparent ...
